Abstract

The asymmetric unit of the title complex, [Co(NCS)2(C7H9N)2(CH3OH)2], comprises of one CoII cation located on a centre of inversion, one thio-cyanate ligand, one methanol ligand and one 3,5-di-methyl-pyridine ligand. The CoII cation is octa-hedrally coordinated by two terminal N-bonding thio-cyanate anions, two methanol mol-ecules and two 3,5-di-methyl-pyridine ligands into a discrete complex. The complex mol-ecules are linked by inter-molecular O-H⋯S hydrogen bonding into chains that elongate in the direction parallel to the b axis.

Summary

Chemical context

The synthesis of new molecular magnetic materials with desired physical properties has been a topic of interest in coordination chemistry (Liu et al, 2015) To reach this goal, paramagnetic cations must be linked by small anionic ligands such as, for example, thiocyanate anions that can mediate magnetic exchange between the cations (PalionGazda et al, 2015; Massoud et al, 2013). Paramagnetic cations must be linked by small anionic ligands such as, for example, thiocyanate anions that can mediate magnetic exchange between the cations (PalionGazda et al, 2015; Massoud et al, 2013) In this context, our group has already reported several thiocyanato coordination polymers which – depending on the metal cation and the neutral co-ligand – show different magnetic phenomena including a slow relaxation of the magnetization (Werner et al., 2014, 2015a,b,c). No single-phase crystalline powder could be synthesized, which prevented further investigations of physical properties
